Method and system for head retraction in a data storage device

摘要

An improved actuation system for a data storage device. In one exemplary embodiment, a head retraction mechanism is movable in a head retraction direction between a head recording position and a head parked position, and an actuator remains engaged with the mechanism for movement during this movement to lessen the risk of damage. A torsional biasing member provides a biasing force on the head retraction arm. A displaceable transmission mechanism is driven by the actuator and moved in a slot in a base from a first position in which the head retraction mechanism is contacted and a second position in which an ejection mechanism is contacted. A load member is integral with the base contacts a friction member on the displaceable transmission mechanism to provide friction for this displaceable movement. The actuator is mounted between a stop member and a biasing member on the base.
